InfiniHost-based InfiniBand HCA adapters are dual-port 10Gb/s PCI-X cards that are designed to drive the full performance of high-speed InfiniBand fabrics. These second generation cards unleash performance with dual 10Gb/s links. These InfiniBand cards are based on an architecture that enables 10Gb/s Database or High Performance Computing (HPC) clustering, and provide the high throughput and low CPU utilization required by these applications. The cards come with either 128 or 256MB of DDR memory.
